Deactivate Account; Friends Lists on Profiles

* Add a way for users to temporarily deactivate their accounts, in a
  recoverable way should they decide to return later.
* A deactivated account may log in but have limited options: to
  reactivate their account, permanently delete it, or log out.
* Fix several bugs around the display of comments, messages and
  forum threads for disabled, banned, or blocked users:
  * Messages (inbox and sentbox) will be hidden and the unread indicator
    will not count unread messages the user can't access.
  * Comments on photos and forum posts are hidden, and top-level threads
    on the "Newest" tab will show "[unavailable]" for their text and
    username.
  * Your historical notifications will hide users who are blocked, banned
    or disabled.
* Add a "Friends" tab to user profile pages, to see other users' friends.
  * The page is Certification Required so non-cert users can't easily
    discover any members on the site.
